700-foot asteroid strike: This horrific thing will happen on Earth to this city

tech.hindustantimes.com:

Asteroids and comets are the biggest threat to humanity in the entire universe. Our entire solar system is filled with these space rocks ranging in size from a few millimeters to hundreds of kilometers. In fact, the largest asteroid in the solar system, Ceres, is 939 kilometers wide. And strangely, we don't even require such humongous asteroids to destroy the Earth amd make humans go extinct. The horrific asteroid that killed all dinosaurs was merely 10 kilometers in size. But what if a monster 700-foot asteroid were to strike Earth tomorrow in the megacity of Los Angeles. How horrific could the damage be? It turns out that we do have a way to predict it.

Answering the above mentioned question with accuracy is difficult because of the vast amount of parameters which need to be considered. But thanks to Asteroid Launcher, an interactive web application designed by coder Neil Agarwal, some of the answers to the question can be found within seconds. The interactive map is part of multiple educational applications which helps you do a bunch of things from solving a trolley problem to even designing the next iPhone.

For this particular experiment, we picked a 700-foot iron asteroid and made it strike the Earth at a speed of 50,000 miles per hour at an angle of 45-degrees in the city of Los Angeles.

The results were quite frightening.

The asteroid strike will instantly create a 3.4-mile wide crater that would go a shocking 1,609 feet deep into the Earth. Just the impact itself would vaporize 63,097 people. Yes, over 50,000 people will be killed instantly. The energy released from the impact would be as intense as 2 Gigatons of TNT. But that's not all. The impact will also create a horrible 4.9-mile wide fireball which will be even
